SPECIFICATION forming part of Letters Patent No. 724,137, dated March 31, 1903.

Application filed June 21, 1902. Serial No. 112,707. (No model.)

To all whom it may concern:

Be it known that I, HENRY 0. SMITH, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Windows, of which the following is a full, clear, and exact description, reference being-had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention isin some respects an improvement upon that described in my application for Letters Patent of the United States of even date herewith and designated Improvement in windows, (Case A, In the said application I have described a window provided with means'by which a sash or sashes of normally closed vertical extension with sides sufficiently secured within the interior facing of the frame to provide a weatherproof joint may be revolved to any degree of opening crosswise the frame without the re-':

moval of any part, and upon the return of the sash to its normally closed position the recessing of its edges within the sides of the frame may be automatically reobtaind and their weatherproof joint therewith automatically reestablished. In the present invention I have shown a window of like organization, but in addition to and in combination with the pivotal movement of the sashes they are also adapted to slide vertically in the frame. Accordingly the invention relates to the means by which sashes may be combined with the frame to slide therein and may also be capable of revolving crosswise the frame to any degree of opening or so that both sides of the sash may be accessible from the same place.

I will now describe the invention in connection with the drawings forming a part of this specification, wherein Figure 1 shows the sashes mainly in vertical section. Fig. 2 shows a detail view in vertical section,of which mention will hereinafter be made. Fig. 3 shows the sashes in horizontal cross-section.

Referring to the drawings, A represents the frame; B and B, the upper and lower sash, respectively. Both are adapted to slide up and down or be revolved crosswise the frame. They are substan tially alike in their construction, and, in so far as it relates to their pivotal organization and to the means by which a sash with normally joint-forming sides-may be swung crosswise the frame, it is substantially like that described and claimed in my application for Letters Patent before referred to. It comprises, therefore, the sash side-rail est'ensions B which are movable-toward and from the remainder of the sash; These side extensions have the exterior outwardly-beveling sides I) b, whichconjoin and form jointed relationship with the groove-forming walls a a of an interior facing and against which the vbeveling sides ofthe extension-pieces are adapted, todraw or wear when the sash is wrenched and they become pressed or forced back into the fixed bodyof the sash. The extension -pieces are supported in their telescopic movement by the pins or bolts b extending crosswise the fixed shell of the sash side and pi nning through their telescopic sides a lateral movement is allowed by the slots 12 0f commensurate length. The sashes are supported in their pivoting by the trunnions 11*.

The trunnions move with the side extensions as they telescope in and out, depending as the sash is revolved open or closed. They extend from the castingsbiwhich not onlysupport the trunnions, but also reinforce the interior shell of the side extension-pieces within which they are contained. The castings b are retained -in place by resting upon the pins b and have the same slots b which are cut through the sides of the extension-pieces to permit of their lateral movement. The trunnions extend through the walls a a at the Opening (1 and during the pivoting of the sash rest for their bearing upon the undercut edge a but when the sash becomes closed or practically closedthat is, so far as its pivotal movement is concerned-they are adapted by their obliquely-extending sides I) to ride up and rest upon the studs (1 supported by the reinforcing-plate a" --The result is therefore obtained that when the extension-pieces which have been pressed in by the pivoting of the sash come in alinement with the grooved interior facing formed in the walls a, a they are drawn out, for the weight of the sash bearing down and resting with the obliquelyextending edges of its trunnions upon the correspondingly beveled edges of the studs is sufficient to draw them out. The trunnions are kept from being withdrawn by openings a within which they have their bearings by the laterally-projecting section Z2 which is extended back of and beyond the edges a of the said openings. The trunnions may, however, be withdrawn by lifting the sash and then withdrawing'them through the upper part of the opening, where it is widened at the point a and this, together with the other features of combination and organization before made mention of, being substantially as described in my application for Letters Patent hereinbefore referred to and to which reference is hereby expressly made for a more detailed consideration and description.

With especial reference now to the construction which permits of sliding of the sashes it is to be observed that the interior walls a a, with which the edges of the sash are adapted to conjoin and which are reinforced by the plates supporting the studs (1, do not form the interior facing to the sides of the frame, but of sliding sections A, contained within its sides. These sliding sections besides their interior walls Ct a have the sides (1 67. They are practically left open, as represented upon their exterior sides, but their tops and bottoms are closed by plates a" c respectively. They are of the same thickness and length as the sash and practically form a continuation of the sash side, that the sash may be contained within the vertically-recessed interior edges of the frame and slide therein just as the ordinary sliding sash operates. The frame may be of any suitable construction and provided with vertical recesses, which are adapted to contain these sliding sections.

In order that the sliding sections A may be locked to, and so practically become a part 'of the sash during its vertical movement, I

have shown the bolts D, which are contained within and adapted to extend from recesses 61, formed, respectively, in the lower rail to the upper sash and the upper rail to the lower sash. These recesses, it is to be observed, are so formed in the metallic shell of each sashrail that the bolts are readily accessible. The bolts are projected to look into the interior walls of the sliding'sections at the points 0 and which, with the trunnions extending through the openings 0. and bearing down obliquely upon the studs a when the sash is in a closed position, as before described, hold the sash locked to the sliding pieces and a vertical movement is made possible.

The sas'hes are in part balanced by weights connected with them, those connected with the upper sash being enough heavier than the weight of the sash to close it upon the release of certain holding-shoes, to be later described, while the weights connected with the lower sash are made enough lighter than its weight that it permits of its closing upon the release of its corresponding holding shoes. The chains which connect the sashes with the weights are attached to the sliding sections A and by any suitable means of attachment.

In order that the sashes may be held in place at any position of adjustment, I have shown the holding-shoes E, which by hearing against the frame side serve to hold the sashes to any position to which they may be opened and as against the tendency of the lower sash to close or of the upper sash to close of its own weight. These shoes comprise a flatheaded end 6, mounted upon arod c, and are held in position by the rods extending through the trunnions b, which extend from the side extension-pieces, as before described, longitudinal openings e being made through the several trunnions. Each shoe is frictionally held with tension against the windowframe by the spring-rod 6 contained in the cavity of the side rail to the sash and which is provided with the bent end 6, where it is united by fusible solder to the sash. The rod 6 is held in position to obtain a bearing against the end of the holding-rod e by the clip a. This clip is held in adjusted position by means of the bolt e, so that the clip and so the rod b supported by it, may be moved laterally and its trunnion upon the end of the holding-rod e varied at will. This result is secured by providing the clip with a threaded hole, as may be obtained from the fixed nut 6 into which the bolt (2 screws. The headed end of the bolt 6 is secured to the interior side of the sash-rail, so that it may be accessible, and secured in such manner as to permit of the bolt being turned in or out. The result is obtained that the clip 6 moves back and forth upon the bolt 6 and so produces a lateral adjustment of the rod e resulting in an increased or diminished tensional bearing upon the end of the holding-rod e, supporting the friction bearing-shoe. As may best be seen from Fig. 1, the rod 6 has an offset at the point a so that the upper section of the rod, which bears against the holdingrod, is away from the center of the section of the rod attached to the sash and passing through the clip a as a center. Upon a release of the rod where it is soldered to the sash at e as in case of fire, the rod turns sufficiently on the clip e as a center that its upper section swings away from the end of the holding-rod, and the tension being removed from the friction bearing shoe the sashes overbalancing or being overbalanced, as before described, automatically close.

The manipulation of the sash is readily obtained. During their vertical movement the sashes practically move as a part'of the sliding sections between which they are contained. They are locked to the sliding sections for security during their vertical adjustment by the projection of the bolts D. When a pivotal movement is desired, these are withdrawn. The sash is then wrenched either at the top or bot-tom, when the laterally moving side extensions, which make jointed connection with the interior facings of the sliding sections, are forced back, the trunnions, which are movablewith them, are simultaneously withdrawn, and the sash may swing crosswise the frame. Upon the return of the sash to a closed position a drawing-out tension is automatically inserted upon the trunnions, as described, and when the side extensions come in alinement with the sliding sections they are then automatically drawn out by the tension inserted upon the trunnions and their jointed engagement with the interior facings of the sliding sections is obtained. The boltsD may then be projected to lock into the sliding sections and the sashes are again in condition for vertical adjustment.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination ofa wind ow-frame hav ing sash holding and guiding recesses, sliding sections contained therein, a sash interposed between the interior facings of said sliding sections and having movable sideextensions which are adapted to make a jointed connection therewith, trunnions or pivots secured to, and movable with said side extensions, and having bearings within the sliding sections and upon which the sash may pivot, means for the automatic withdrawal of said side extensions from their jointed connection with the sliding sections upon the pivoting of the sash, that the same may swing crosswise the frame, and means for automatically extending them, that the jointed connection aforesaid may be obtained with the sliding sections when the sash has become approximately closed, substantially as described.
